25(OH)2D within the kidney is tightly regulated in response to serum ionised calcium (Ca2+) levels. This occurs in conjunction with parathyroid hormone (PTH) and fibroblast growth factor-23 (FGF-23). Low Ca2+stimulates the release of PTH, which simultaneously increases renal calcium reabsorption...

Vitamin D levels are alarmingly low (<75 nmol/L) in 65-70% of North American children older than 1 year. An increased risk of viral upper respiratory tract infections (URTI), asthma-related hospitalizations and use of anti-inflammatory medication have
Serum 25(OH)D (1 ng/mL = 2,5 nmol/L) is the barometer for the medical laboratory evaluation of the vita- min D status.1-3 25(OH)D is then converted in the kidneys via the enzyme 25-hydroxyvitamin D-1-α-hydroxylase also known as cyto- chrome p450 27B1 (1-OHase: CYP27B1) ...
We found that total 25(OH)D was strongly influenced by age, and that light coloured sheep had higher 25(OH)D3 (but not 25(OH)D2) concentrations than dark sheep. The coat colour polymorphism in Soay sheep is controlled by a single locus, suggesting vitamin D status is heritable in this...
Vitamin D deficiencies are linked to multiple human diseases. Optimizing its synthesis, physicochemical properties, and delivery systems while minimizing s
It is well known that low serum levels of 25(OH)D are associated with a significant decrease in the absorption of intestinal calcium and may induce secondary hyperparathyroidism, which could potentially stimulate the transformation of pre-osteoclasts into mature osteoclasts and lead to osteoporosis and...

(RCT) of 782 Danish children and adults, fortified milk and bread (9.4 μg/day total vitamin D intake compared with 2.2 μg/day for control foods) successfully prevented a decrease in serum 25(OH)D concentration over winter and allowed maintenance of serum 25(OH)D in children >50 nmol ...
